When did we get the idea that biometrics were such a great idea? We literally wear our new "passwords" on our fingerprints all the time. We also leave fingerprints around, basically meaning we simply rely on people being too lazy to find a way to replicate them.<p>Secondly, you can't change biometrics. That's bad. Your retinae, fingerprints, etc. can't be reset if stolen.<p>Finally, there's a lot more legal precedent for passwords. As it stands, passwords are protected as "persons and papers", while fingerprints etc. are not.<p>Biometrics seem like an attempt to try to compensate for people's reluctance to make good, unique passwords. This is the cynic's opinion, but I don't think we can ever compensate completely for the human fallibility of any system.
